Webb10 maj 2013 · TMPRSS2 (transmembrane serine proteinase 2) is a multidomain type II transmembrane serine protease that cleaves the surface glycoprotein HA (haemagglutinin) of influenza viruses with a monobasic cleavage site, which is a prerequisite for virus fusion and propagation. Furthermore, it activates the fusion protein F of the human … Webb13 apr. 2024 · Transmembrane Protease Serine 2 (TMPRSS2) is a type II transmembrane, trypsin-like endopeptidase expressed in the respiratory system and small intestines [53, 54]. Its role in priming the spike protein of some SARS-CoV and SARS-CoV2 and in assisting the virus-cell fusion has been demonstrated [51, 55].
WebbEfficient host cell entry then depends on: (i) cleavage of the S1/S2 site by the surface transmembrane protease serine 2 (TMPRSS2); and/or (ii) endolysosomal cathepsin L, which mediate virus–cell membrane fusion at the cell surface and endosomal compartments, respectively. Webb6 maj 2024 · The host cell serine protease TMPRSS2 is an attractive therapeutic target for COVID-19 drug discovery. This protease activates the Spike protein of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and of other coronaviruses and is essential for viral spread in the lung.
